The exact shape of the intracavity dispersion is predicted to have a large influence on the mode-locking characteristics and spectral shape of the output pulses of Ti:sapphire chirped-pulse oscillators. We have experimentally investigated the influence of the exact shape of the intracavity dispersion on the operation of such oscillators. Our experimental results are in good agreement with the theoretical...
The effects of higher-order dispersions (HOD) on the chirped-pulse oscillator (CPO) stability have been analyzed numerically. It was found, that a local spectral maximum of group delay dispersion (GDD) as well as a "slope" in the frequency-dependence of GDD suppress the stability. On the contrary, a GDD local minimum strengthens the stability. A character of the destabilization changes in...
Femtosecond pulse train with self-stabilized carrier envelope offset phase is generated near the center of the gain band of Ti:sapphire at full repetition rate of oscillators by using difference frequency generation
